locked publications?

[The Little One]

My church runs a small network - just three PCs all running Windows XP and
Office 2000.

They have recently started having a problem with Publisher files. If you
start a publication on machines 2 or 3, it can be opened by all machines.
However if you start a publication on machine 1, or save an existing
publication with a new name, it cannot be opened by the other computers. It
displays a message that the file is in use by another user, even though it
definately isn't.

My guess is that, machine 1 is not removing some sort of lock file, but I
wouldn't know how to check if this is true.

Does anyone have any ideas why this is happening or things that I could
check for?

Thanks.
